Dual Precision, 17 MHz, Low Noise, CMOS Input Amplifier
The SM73307 is a dual, low noise, low offset, CMOS input,
rail-to-rail output precision amplifier with a high gain band-
width product. The SM73307 is ideal for a variety of instru-
mentation applications including solar photovoltaic.
Utilizing a CMOS input stage, the SM73307 achieves an input
bias current of 100 fA, an input referred voltage noise of 5.8
nV/ , and an input offset voltage of less than ±150 μV.
These features make the SM73307 a superior choice for pre-
Consuming only 1.30 mA of supply current per channel, the
SM73307 offers a high gain bandwidth product of 17 MHz,
enabling accurate amplification at high closed loop gains.
The SM73307 has a supply voltage range of 1.8V to 5.5V,
which makes it an ideal choice for portable low power appli-
cations with low supply voltage requirements.
The SM73307 is built with National’s advanced VIP50 pro-
cess technology and is offered in an 8-pin MSOP package.
The SM73307 incorporates enhanced manufacturing and
support processes for the photovoltaic and automotive mar-
ket, including defect detection methodologies. Reliability
qualification is compliant with the requirements and temper-
ature grades defined in the Renewable Energy Grade and
Unless otherwise noted, typical values at VS = 5V.
